Title: Semiconductor laser device
Inventor: KUME MASAHIRO
IPC: H01S5/00
Filed: 1985-02-08
Abstract: PURPOSE:To diminish the temperature-dependancy in sensitivity of a photo diode by a method wherein the title device is constructed by providing the semiconductor laser part with two parallel ridges on both sides of a V-groove and the photo diode part with only steps. CONSTITUTION:A ridge is prepared on a P-type GaAs substrate 1, and an N-type GaAs layer 2 is grown by liquid phase epitaxial growth so that the surface becomes flat by covering the ridge up. A groove is formed again, and ridges are prepared on both sides of the V-groove at the semiconductor part. A step is formed at the photo diode par by etching only one side of the groove. Successively, a double hetero junction is grown. At this time, the semiconductor laser part is inhibited in growing speed over the ridge by the ridge effect and therefore gets the Al mixed crystal ratio increased more than in the photo diode part during the growth of the active layer 4. Accordingly, the active layers of the semiconductor laser part and the photo diode part can be supplied with different energy gaps with the same growing solution. After crystal growth, a resonator surface is prepared at the part corresponding to oblique lines in the figure.

Title: Controller of directional antenna mount for ship or the like
Inventor: KITAGAMI MITSUMASA
IPC: G05D1/08
Filed: 1980-02-29
Abstract: PURPOSE:To facilitate an easy control for a high elevation angle, by turning the antenna to the zenith in case when the direction of a satellite is within a half-value angle of the beam centering on the zenith when viewing the satellite from a ship. CONSTITUTION:A comparison is given between the difference theta1 of the elevation angle theta of the position of satellite when viewed from a ship and the zenith (theta=90 deg.) and the angle theta2 of 1/2 half-value angle of the antenna's beam. In the case of theta1> theta2, a directional control is given to the antenna based on the information of the pitch and roll of the ship plus the azimuth of the satellite. While the antenna is turned to the zenith in the case of theta1<theta2. The maximum directive error to the satellite is set within theta2, and thus an assured tracking is possible to the artificial satellite. Furthermore a miniaturization is realized for the driving system since a quick rotation becomes unnecessary for the axis AZ even with a high elevation angle.

Title: Image compressing method and mail processing system using it
Inventor: TOMOKANE TAKEO
IPC: H04N19/18
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To fast compress an image and to suppress image deterioration as much as possible by at least estimating the data size of encoded data, comparing it with code quantity that is estimated for the maximum code quantity, increasing the quantization value of a quantization table, requantizing an orthogonal transformation coefficient after quantization and suspending Huffman coding when coded data reach the maximum code quantity. SOLUTION: Estimated code quantity is calculated by scanning a DCT coefficient block after the whole image data are quantized. The estimated code quantity is compared with the maximum code quantity of an image compressor, and if the estimated code quantity is <= the maximum code quantity, it proceed to the process of Huffman coding. When the estimated code quantity is larger, all of quantization values of a quantization table are doubled. For instance, next, requantization processing of the quantization of DC and AC components of a DCT coefficient block after quantization, is performed. Processing is performed in every DCT coefficient block after quantization. When the DCT coefficient is positive, the value of the DCT coefficient is shifted by one bit to the right.

Title: Fluidized bed type heat exchanger
Inventor: KOMAGINE TAKASHI
IPC: F28D13/00
Filed: 1982-02-18
Abstract: PURPOSE:To prevent the scattering of particles of a particle layer by a method wherein fins are attached to a heat transfer tube arranged in an empty tower section of the titled heat exchanger such that the fins are inclined toward the direction of the upward flow of a high temperature flowing through the heat transfer tube with the terminating ends of the adjoining fins overlapped one another. CONSTITUTION:The fins 10 are attached to the heat transfer tube 7a arranged in the empty tower section 6 of the heat exchanger in such a manner that the fins are inclined with respect to the direction of the upward flow of the high temperature fluid A with the terminating ends of the adjoining fins overlapped one another. With the above structure, when the high temperature fluid A passes through the particle layer 5, scattering particles run gainst the inclined and overlapped fins 10 and fall down. Accordingly, the particles 5 do not scatter and the height of the empty tower section 6 of the heat exchanger can be reduced so that no wire netting for preventing the scattering of the particles is required and the resistance against the flow of the high temperature fluid A is reduced to thereby improve the heat exchange efficiency of the heat exchanger.

IPC: G01S1/72
Filed: 1987-02-04
Abstract: PURPOSE:To simplify a circuit by calculating the inner products of NS and omnidirectional, and EW and omnidirectional complex spectral vectors and dividing them by the absolute value of the omnidirectional complex spectral vector, and finding an approximate value of an absolute value with a sign. CONSTITUTION:Received signals of NS, EW, and omnidirectional receives are processed by Fourier transformation to find the complex spectral vectors respectively. The real parts and imaginary parts of the respective vectors are inputted to an inner product calculating circuit 1 to calculate the inner products 55 of the NS and EW, and omnidirectional vectors. Then a dividing circuit 2 divides the inner product 55 by the omnidirectional absolute value 57 which is already calculated to obtain an absolute value output 56 with a NS or EW sign. This absolute value 56 with the sign is the value obtained by approximating a coefficient +1 or -1 by cos(NS or EW phase difference). Consequently, the calculation quantity is reduced and the circuit is simplified.

IPC: H01F27/28
Filed: 1979-03-06
Abstract: PURPOSE:To prevent the breakage of the layer insulator and dielectric breakage by inserting a spacer attached insulating paper board between layers of the multiplex winding coil. CONSTITUTION:Tap leads 12, covered by insulating tubes 13, are let out from inner layers 11 of the multiplex winding coil. In the case when the next winding is wound on the tap leads 12, it causes a difference in level. So spacers 22 whose width A' is a little wider than the width A of tap leads 12, are attached to the insulating paper board 21, on which a layer insulator 14 is wound around and the next coil is then wound around on the outside. In such a way as above-mentioned, the layer insulator 14 is uniformly wound as far as to the edge of layer and almost up to the same height as that of the tap leads, on the coil surface on the side of the tap lead. Therefore, there is no anxiety of having a difference in level, and there occurs no damage when the coil of the next layer is wound on it, therby maintaining a stabilized voltage-withstanding characteristic.
